The Use of Carbon Fiber Implants for Impending or Existing Pathologic Fractures

Area of Science:

• Orthopedic surgery
• Biomaterials science
• Medical device engineering

Background:

• Pathologic fractures require stabilization with intramedullary implants.
• Carbon fiber implants (CFIs) and titanium alloy (TI) are used for this purpose.
• Complications and utility require comparative evaluation.

Purpose of the Study:

• To compare the utility and complication rates of CFIs versus TI intramedullary implants.
• To evaluate outcomes in patients with impending or existing pathologic fractures.

Main Methods:

• A retrospective comparison of 94 patients with 100 pathologic fractures treated between 2014-2019.
• Analysis of postoperative complications as the primary outcome.
• Comparison of implant type, pathology, indication, and adjuvant therapy.

Main Results:

• Fifty-three percent of cases used CFIs, 47% used TI implants.
• No significant differences in postoperative complications (19% in each group) or complication types were observed between CFI and TI groups.
• Titanium alloy implants provided a cost saving of $400 per case compared to CFIs.

Conclusions:

• Both CFIs and TI implants demonstrate comparable complication profiles for stabilizing pathologic fractures.
• Implant selection should consider patient-specific factors and surgeon preference.
• Titanium alloy implants present a cost-effective alternative.
